摘要： 通过对鄂尔多斯盆地东南缘煤和煤层夹矸进行抽提, 得到其抽提物氯仿沥青A, 然后对氯仿沥青A 进行微量元素和稀土元素测试分析, 提供一些地球化学信息, 以此来揭示鄂尔多斯盆地东南缘煤中的一些地球化学特征。认为鄂尔多斯盆地东南缘煤的形成原始物可能主要来自上地壳。

Abstract: Chloroform bitumen A has been extracted from coal and coal gangue in southeastern margin of Ordos basin. The trace elements and rare earth elements in it are tested and analyzed, which provide some geochemical information for revealing the geochemical characteristics of coal in this area. The study suggests that the original materials for forming coal in southeastern margin of Ordos basin are most likely from the upper crust.

Key words: Ordos basin, coal, bitumen, trace element, rare earth element
